RFC 7163

RFC 7163: URN for Country-Specific Emergency Services 🚨✨

okay bestie, let's get into this 💅 It's a Standards Track doc from March 2014, written by C. Holmberg and I. Sedlacek at Ericsson 🎀. The whole point is that it updates RFC 5031 (the Updates: 5031 part), so it's changing some of that older doc's rules. The ISSN is 2070-1721.

Abstract 🌸

This doc updates the registration guidance in Section 4.2 of RFC 5031. That guidance lets people register service URNs with the 'sos' service type only for emergency services "that are offered widely and in different countries." This update loosens that so a service can be registered when, at the time of registration, it's only offered in one country 🌍.

1. Introduction 🌷

okay so the advice for experts on registering sub-services of the service URN with the 'sos' service type is in Section 4.2 of RFC 5031 [RFC5031], and it goes like this:

   The 'sos' service type describes emergency services requiring an
   immediate response, typically offered by various branches of the
   government or other public institutions.  Additional sub-services
   can be added after expert review and must be of general public
   interest and have a similar emergency nature.  The expert is
   designated by the ECRIT working group, its successor, or, in their
   absence, the IESG.  The expert review should only approve
   emergency services that are offered widely and in different
   countries, with approximately the same caller expectation in terms
   of services rendered.  The 'sos' service is not meant to invoke
   general government, public information, counseling, or social
   services.

Some existing emergency services are, at least at first, only offered in one country 🇰🇷🇨🇴. Examples are the "Reporting spies" emergency service in South Korea and the "GAULA (anti-kidnapping)" emergency service in Colombia, according to [WIKIPEDIA]. Future emergency services might also start out in just one country, iykyk 🧚.

The advice to experts for sub-services of the 'sos' service URN in RFC 5031 [RFC5031] stops the registration of any sub-service for a service that, at registration time, is offered in only one country. Kinda rude, honestly 🙈.

So this document updates the 2nd paragraph of Section 4.2 of RFC 5031 [RFC5031], so that registering 'sos' service URNs is allowed for emergency services that, at registration time, are offered in only one country. Slay 💅✨

2. Conventions 🎀

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14, RFC 2119 [RFC2119].

3. Update to RFC 5031 🍓

3.1. General 🧚

Section 3.2 of this document replaces the text of the 2nd paragraph of Section 4.2 (Sub-Services for the 'sos' Service) of RFC 5031 [RFC5031].

3.2. New Text Replacing the Text of the 2nd Paragraph of Section 4.2 of RFC 5031 💜

   The 'sos' service type describes emergency services requiring an
   immediate response, typically offered by various branches of the
   government or other public institutions.  Additional sub-services can
   be added after expert review.  The expert is designated by the ECRIT
   working group, its successor, or, in their absence, the IESG.  The
   designated expert should only approve services that are to be used
   for emergency purposes, that are offered in at least one country,
   that do not match the description of any existing service URN with
   the 'sos' service type, and where the service description and the URN
   are defined as broadly as possible to encourage reuse.  The 'sos'
   service is not meant to invoke general government, public
   information, counseling, or social services.

4. IANA Considerations 🌈

This document updates the advice to the expert of the "'sos' Sub-Services" registry. IANA has updated the reference for that registry to point to this document (instead of RFC 5031 [RFC5031]):

<http://www.iana.org/assignments/urn-serviceid-labels>

5. Security Considerations 🔐

This document does not update the Security Considerations of RFC 5031.
